Origins and Evolution of the 68RFE Transmission
The 68RFE was introduced in 2007 as an optional transmission for the Dodge Ram 2500 and 3500 trucks. Chrysler developed the 68RFE in response to the growing demand for heavy-duty trucks capable of handling large loads and towing efficiently. Before the 68RFE, Chrysler used several other transmissions, such as the 45RFE, 545RFE, and 65RFE, which were modified versions of existing transmissions. However, the 68RFE was the first transmission specifically developed for heavy-duty vehicles, incorporating new features and technologies for improved durability and performance.
Since its introduction, the 68RFE has undergone several updates. In 2009, Chrysler enhanced the transmission’s software to improve shift quality and reduce shift time, making it even more capable of handling heavy-duty use. In 2011, the transmission received a strengthened input shaft and a new torque converter, further boosting its towing performance. More recently, the 68RFE has been adapted for use in other Chrysler vehicles, such as the Ram 1500 and Jeep Grand Cherokee, expanding its impact on the heavy-duty market.
